Elena would likely be angry. She has her own agency and doesn't like being controlled. If Stefan kidnapped her, she would fight back. She might use her knowledge of the supernatural world and her relationships with other characters to try to escape. For example, she could try to call out to Damon telepathically if they have some sort of connection in the story.
I'm sorry, I haven't read this specific fanfiction. But you can try to find it on popular fanfiction websites like Archive of Our Own or Fanfiction.net.
One common theme is the idea of eternal love. Since they are in a supernatural world, their love is often depicted as something that can transcend time and death. For example, in many fanfictions, even if one of them is in danger or seemingly lost, their love remains unwavering.
Caroline, for example, might be more accepting as she is also a vampire. She could help Elena adjust to her new life. Damon, on the other hand, might be jealous or feel threatened that Stefan made Elena a vampire. It could change the power balance between the three of them.
There are many fanfiction platforms out there, but promoting or suggesting fanfiction with sexual content is not ethical. However, if you are interested in Stefan and Elena's story in a non - sexual way, you can check out Archive of Our Own. They have a wide variety of fanfictions that explore different aspects of their relationship, like their love - hate dynamic in a more appropriate manner.
One possibility is that Stefan is under some dark spell or influenced by an evil force. Maybe he kidnaps Elena to protect her from a greater danger that he believes only he can handle, but his actions are misinterpreted. For example, there could be a new vampire hunter in town who has a special weapon that can kill vampires instantly, and Stefan thinks the only way to keep Elena safe is to take her to a hidden location.
The consequences could be complex. On one hand, they might grow closer as they face the challenges of Elena's new existence. But on the other hand, Elena might struggle with her new identity and blame Stefan for turning her. This could create tension and strain in their relationship.
Another plot could be that the baby has some unique supernatural abilities that neither Stefan nor Elena expected. This could lead to them having to search for answers about the baby's powers. They might seek help from their friends like Caroline and Damon. Along the way, they encounter various characters who either want to help or harm the baby because of its special nature.
One great Elena and Stefan fanfiction is 'A New Beginning'. It explores their relationship in a different light, where they face new challenges together in a world where vampires and witches co - exist more peacefully. It has a lot of sweet moments between them that will surely satisfy fans.
Love and passion are common themes. Writers often focus on the intense emotions that Stefan and Elena have for each other. Another theme could be redemption. Maybe one of them has made mistakes in the past and through their love, they find a way to redeem themselves.
